Polymer80 P80-Jig-RL556V3 Jig Kit

For builders who demand precision and repeatability in their AR-15 platform projects, the Polymer80 P80-Jig-RL556V3 Jig Kit delivers a complete, ready-to-use solution for finishing your 80% lower receiver. This jig kit eliminates guesswork and provides the exact guide paths required for a professional-grade build. Whether you are a first-time builder or an experienced gunsmith, this kit is engineered to meet the rigorous standards of the Polymer80 ecosystem.

Overview

The Polymer80 P80-Jig-RL556V3 jig kit is a dedicated tooling system designed for use with Polymer80 80% lower receivers. It includes all necessary drill guides, router templates, and alignment fixtures to complete your lower receiver at home. The kit is built for the AR-15 platform and accepts standard mil-spec parts after finishing. This is not a generic multi-platform jig; it is specifically calibrated for the Polymer80 RL556v3 frame geometry, ensuring correct trigger pocket depth, fire control group placement, and pin hole alignment. Each component is machined from high-impact polymer and hardened steel bushings to maintain accuracy over multiple builds.

Features & Specs

• Complete jig kit including drill guide blocks, router template, alignment pins, and step-by-step instruction sheet. No additional jigs or fixtures required for the RL556v3 lower.
• Hardened steel drill bushings precisely positioned to guide bits at correct angles for trigger pin, hammer pin, and safety selector holes. Bushings are replaceable for extended service life.
• Reinforced polymer main body with anti-slip clamping system that secures the 80% lower in three axes. Reduces vibration during machining and prevents frame movement.

The kit is compatible with standard hand drills, drill presses, and plunge routers. All cutting paths are pre-mapped to match the Polymer80 RL556v3 pocket dimensions. Manufacturer specifications list this as a Build Kit category item, intended for end-user assembly with appropriate tools and skills.

Who It’s For

This polymer80 p80-jig-rl556v3 jig kit is intended for individuals who legally possess an unfinished 80% lower receiver and have the required tooling to complete the machining process. It is suitable for hobbyists who prefer hands-on assembly, custom builders creating unique configurations, and gunsmiths who need a reliable, repeatable jig for client builds. The kit is not a firearm and does not contain serialized parts. You must be at least 18 years of age to purchase this product. No special licensing is required for personal use, provided you comply with all applicable federal, state, and local laws regarding firearm manufacture.

If you already own a Polymer80 RL556v3 lower and want a dedicated jig that matches its exact specifications, this kit eliminates the trial-and-error common with universal templates. It is also ideal for builders who plan to complete multiple lowers and require a durable jig that maintains alignment over time.

Shipping & FFL

No Federal Firearms License (FFL) transfer is required for this product because it is a tooling kit, not a firearm or firearm receiver. However, the finished lower receiver you create from an 80% blank is subject to federal law: it may not be transferred or sold without a serial number and compliance with all applicable regulations. You are solely responsible for ensuring your use of this kit complies with local, state, and federal laws. We recommend consulting with a legal professional if you have questions about the legality of manufacturing a firearm in your jurisdiction. By purchasing this item, you confirm that you are legally permitted to own and operate the necessary machining tools and that you will not manufacture a firearm in violation of the law.
